An intervention in Wisconsin GOP's Koch Addiction.

Wisconsin Democrats have had enough with the overwhelming flow of dark money coming into their state to prop up Gov. Scott Walker (R) and are taking their fight direct to the source: David Koch.

On a conference call with reporters yesterday, Wisconsin Democratic Party Chairman Mike Tate announced the party was filing a compliant with the state Government Accountability Board, which oversees elections in the state, and forwarding a copy of the compliant to the Internal Revenue Service attacking the nonprofit status of Americans For Prosperity after recent comments Koch made in a Florida paper.

“These organizations are a farce,” said Tate, referring to AFP’s 501(c)(3) status, as well as that of a state level conservative organization the MacIver Institute. “This designation allows an organization to accept tax-deductible contributions and further provides that they are not required to disclose their donors, nor are they required to report their spending until after an election has taken place.”

He added: “But to maintain this status, a 501(c)(3) is prohibited from engaging in ‘activities which constitute participation or intervention in a political campaign on behalf of or in opposition to a candidate.’”
